Description

Technical Field

[0001] This utility model belongs to the technical field of resin processing equipment, and more specifically, it relates to a rapid precipitation and washing device for cyanate ester resin prepolymer. Background Technology

[0002] Cyanide resin is a type of high-performance thermosetting resin. Due to its low dielectric constant and high heat resistance, it is widely used in fields such as electronic packaging and aerospace composite materials. In the preparation process of cyanide resin prepolymer, precipitation and washing are key steps that determine the purity and performance of the product.

[0003] Application number CN202222954584.9 discloses a reactor for processing cyanate ester resin, belonging to the field of synthesis reactor technology. It includes a reactor body, a mixing mechanism, and a sampling mechanism. The sampling mechanism is characterized by a shell fixedly installed on the top of the reactor body, with its interior communicating with the interior of the reactor body to ensure the reactor body's airtightness. To solve the sampling problems existing in prior art reactors, this invention uses a gear installed inside a sealed cavity to rotate, causing a rack fixedly installed on the side wall of a sleeve to move downwards. This, in turn, causes a sampling tube penetrating the inside of the sleeve to move downwards. When the sampling tube contacts the reaction liquid, the gear rotation stops, and an air pump evacuates the inside of the sampling tube into a vacuum. The reaction liquid flows along the sampling tube through a connecting pipe and into a collection box, completing the sampling process. This ensures a sealed process during sampling. After sampling, a solvent connected to a spray nozzle sprays and cleans the bottom of the sampling tube and the sleeve, ensuring the accuracy of the next sampling.

[0004] Based on the above patent search and understanding of existing applications of cyanate ester resin prepolymer precipitation and washing: In the existing process of preparing cyanate ester resin prepolymers, the equipment for precipitation and washing processes lacks an effective sealing structure. The openings in the equipment during the material addition stage can easily lead to solvent evaporation, causing not only serious environmental pollution but also harming the health of operators.

[0005] In traditional sedimentation equipment, insufficient material mixing uniformity leads to low reaction efficiency, slow resin prepolymer sedimentation, and uneven spraying of cleaning solution during the washing process, making it difficult to fully cover the inside of the sedimentation tank, resulting in poor washing effect and residual impurities affecting product purity. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a rapid precipitation and washing device for cyanate ester resin prepolymers. This addresses the issues of existing equipment lacking effective sealing structures for the precipitation and washing processes in the preparation of cyanate ester resin prepolymers, leading to solvent evaporation during material addition, causing serious environmental pollution and harming operator health; insufficient material mixing uniformity in traditional precipitation equipment resulting in low reaction efficiency and slow resin prepolymer precipitation; and uneven spraying of the washing solution during the washing process, making it difficult to fully cover the interior of the precipitation tank, resulting in poor washing effects and residual impurities affecting product purity.

[0007] The technical solution adopted in this utility model is as follows: A rapid sedimentation and washing device for cyanate ester resin prepolymer includes a vessel body; a sedimentation tank is fixedly installed in the middle of the interior of the vessel body, the top front end of the sedimentation tank is fixedly connected to the bottom of the addition tube, and the addition tube passes through the front of the interior of the vessel body; a limiting frame is fixedly installed in the lower middle of the interior of the addition tube, the top middle of the limiting frame is fixedly connected to the bottom middle of the elastic telescopic rod, the top middle of the elastic telescopic rod is fixedly connected to the bottom middle of the conical plug, an annular rubber ring is fitted on the conical part of the conical plug, and a conical groove that is narrower at the top and wider at the bottom is provided in the upper part of the interior of the addition tube, so that when the elastic telescopic rod is in the extended state, the conical plug fits into the conical groove of the addition tube.

[0008] According to one embodiment of the present invention, a motor is fixedly installed at the top center of the vessel body, and the motor shaft is fixedly connected to the top center of the stirring rack, which is located inside the sedimentation tank at the center.

[0011] According to one embodiment of the present invention, a pump body is fixedly installed at the rear end of the vessel body, and the pump body is connected to an annular nozzle component through a water pipe. The annular nozzle component is located on the outer side of the water wheel.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The addition tube uses an elastic telescopic rod that works in conjunction with a conical plug. When material is added, gravity presses down on the conical plug to open the channel. After addition is complete, the elastic telescopic rod automatically resets to achieve a seal, effectively avoiding environmental pollution and health hazards caused by solvent evaporation, and improving the safety and environmental protection of the operation.

[0013] 2. The stirring rack is driven by a motor to rotate inside the settling tank, which fully stirs the material, promotes uniform reaction, significantly improves the settling speed of cyanate ester resin prepolymer, and shortens the production cycle.

[0014] 3. The cleaning solution is delivered to the annular nozzle by the pump body. With the help of the water wheel driven by the motor shaft and the bottom circular diverter plate, the cleaning solution is evenly dispersed and covers the inside of the sedimentation tank, achieving all-round and efficient washing, reducing residual impurities and ensuring product purity.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a rapid sedimentation and washing device for cyanate ester resin prepolymer, including a vessel body 1; a sedimentation tank 101 is fixedly installed in the middle of the interior of the vessel body 1, the top front end of the sedimentation tank 101 is fixedly connected to the bottom of the addition pipe 2, and the addition pipe 2 passes through the front of the interior of the vessel body 1. A limiting frame 201 is fixedly installed in the lower middle of the interior of the addition pipe 2, the top middle of the limiting frame 201 is fixedly connected to the bottom middle of the elastic telescopic rod 202, the top middle of the elastic telescopic rod 202 is fixedly connected to the bottom middle of the conical plug 203, and an annular rubber ring is fitted on the conical part of the conical plug 203. A conical groove that is narrow at the top and wide at the bottom is provided in the upper part of the interior of the addition pipe 2. When the elastic telescopic rod 202 is in the extended state, the conical plug 203 fits into the conical groove of the addition pipe 2.

[0025] Among them, a motor 102 is fixedly installed at the top center of the vessel body 1, and the rotating shaft of the motor 102 is fixedly connected to the top center of the stirring rack 103. The stirring rack 103 is located at the inner center of the sedimentation tank 101.

[0026] The sedimentation tank 101 is equipped with a discharge valve 104 at the bottom. The discharge valve 104 is located at the middle of the bottom of the vessel body 1, and the vessel body 1 and the sedimentation tank 101 are designed with a sandwich space.

[0027] Among them, a water wheel 105 is fixedly connected to the lower part of the rotating shaft of the motor 102, and a circular diverter plate is provided at the bottom of the water wheel 105. The water wheel 105 is located inside the sedimentation tank 101 at the upper part.

[0028] A pump body 106 is fixedly installed at the rear end of the vessel body 1. The pump body 106 is connected to an annular nozzle 107 through a water pipe. The annular nozzle 107 is located on the outside of the water wheel 105.

[0029] When using: The cyanate ester resin prepolymer is added into the addition tube 2 to prepare the relevant materials. Under the action of gravity, the material presses down on the conical plug 203, causing the elastic telescopic rod 202 to contract. The conical plug 203 separates from the conical groove of the addition tube 2, and the material smoothly enters the sedimentation tank 101. After the material is added, the elastic telescopic rod 202 returns to its extended state, causing the conical plug 203 to re-fit against the conical groove to achieve a seal. This avoids the situation where the addition process is exposed to the air and causes solvent evaporation, which would result in serious environmental pollution and harm to the health of the operators.

[0030] Start the motor 102 at the top of the vessel 1. The rotating shaft of the motor 102 drives the stirring rack 103 to rotate inside the sedimentation tank 101, which fully stirs the material, promotes the material reaction and rapid sedimentation. Open the discharge valve 104 at the bottom of the sedimentation tank 101 to discharge the resin that has completed sedimentation.

[0031] The pump 106 at the rear end of the vessel 1 is started. The pump 106 delivers the cleaning solution to the annular nozzle 107 through the water pipe. The annular nozzle 107 sprays the cleaning solution into the sedimentation tank 101. At the same time, the shaft of the motor 102 drives the water wheel 105 to rotate. The circular diverter plate at the bottom of the water wheel 105 evenly disperses the sprayed cleaning solution, thoroughly washing the inside of the sedimentation tank 101. After washing, the discharge valve 104 at the bottom of the sedimentation tank 101 is opened to discharge the cyanate ester resin washing waste liquid, completing the entire sedimentation and washing process.
